SPECIFICATION forming part of' Letters Patent No. 497,704, dated May 16, 1893.

Application filed July 21, 1892 Serial No. 440,736. (No modal.) Patented in England June 8,1889, No. 285, and in France June 8, 1889.110. 198,814.

To all whom u may concern:

Be it known that I, JEAN BAPTISTE GUSTAVE ADOLPHE CANET, engineer, a citizen of the Republic of France, and a resident of Paris,

- France, have invented certain new and use- .ful Improvements in Gun-Mountings, (for which I have obtained patents in the following. countries, viz: Great Britaim-NO. 285 of- 1890, but dated under the" international convention as of June 8, 1889, and France, No.

198,814, dated J une 8,1889) of which the following is a specification, reference being had to the accompanying drawings. This invention relates to gun mountings t 5 and comprises improved mechanism for working and loading the gun, the chief object of the invention being to increase the facility for working the gun so asto render this operation easy and rapid.

my invention applied to -a' quick-firing gun although it is obvious that it may be applied to guns of other types.

Like throughout the drawings. 1

The gun 'A is mounted in a cradle B to which it is secured by keys, and is prevented from sliding therein by collars A Fig. '2

formed on the gun and corresponding grooves in the cradle in which the said collars rest.

The cradle 13 Fig. 1 carries the brake and the parts for running the gun out. It is mounted to slide on a frame 0 which is supported at its forward end by trunnions C Fig. 3 which rest in bearings formedin a pillar-D.

E E are the brake cylinders which arecar- In the accompanying drawingsl have shown Fig..4 is' letters indicate cdrresponding partsried by the cradle B. The brake piston rods 5o E are-attached at their forward endsto the frame 0." V "Any suitable system of.hydraulio brake may be employed in combination with my improved recuperatorapparatus hereinafter '5 5 described. The trunnion's are situated in a plane passing through the axis of the gun and the axes of-the brake cylinders, thereby avoiding all chance of tilting of the frame C when the gun is fired. The pillar D is sup- 6o ported by conical or spherical rollers orballs' F Fig. 2 which roll upon abed plate G. The

bed plate Gis provided with an annular part G Fig. 2 that forms a pivot on which the pillar D'can turn. The said pillar D is of I cylindro-conical'form closedat the front and sides for the purpose of protecting the workingparts of the mounting. i For supporting the rear end of the frame 0' and for effecting the vertical pointing of the gun I provide as follows: H, H Fig. 3 are curved toothed racks or sectors arranged on each side of'the mounting and pivoted at their lowerends to the'pillar D at H H. The Y upper ends of the said racksor sectors slide 5 through guides H H? fixed to the frameO. The racks are so placed that they have the same center of curvature as the trunnions 0.

Consequently the frame Gwhen raisedand lowered does-not afie'ct the inclination ofthe 8o toothed sectors. H, H are brackets fixed to the frameC and forming bearings for a shaft H on which is keyed a pair of spur wheels I-I Figs. 2 and 4 that gears with the toothed sectors H. H isa worm wheel also keyed on the shaft H and gearing with aworm orend-.

less screw'H which is mounted on an inclined shaft H and connected-therewithby a feather key in such a manner as to be compelled to rotate with the shaft 'while being capable of. go sliding thereon. The said shaft H is hinged at H to the upper end of theiadjoining sector H so as tobe capable of swinging about its pivot as the frame 0 moves up and down. 1-1 is a hand wheel carried. .blyithe sector 1-1 5 and geared to the shaft H by a pair of wheels H -Fig. 1 through which the said shaft may be rotated to vary the elevation of the gun.

ed on a shaft K which is geared through a worm K worm wheel K vertical shaft K and pinion 1' Fig. 3 with a toothed ring K fixed on the base plate or bed G. The lateral training may also be effected by a motor J which is geared to the shaft K by gear wheels J.

My loading mechanism which enables the charges to be raised from the magazine and conveyed behind the breech in whatever position the gun may be trainedis constructed as follows: On studs fixed in the side of the frame C I mount a pair of chain wheels L* Fig. 3 which are connected by a chain L. To the side of the cradle B I pivot a tappet or catch L which is free to turn in one direction but is prevented by a stop L from turning inthe other direction. The said catch engages with the chain L when the gun is running out and drags the chain round, but in the recoil the catch turns on its pivot and slides over the chain withoutmoving it. On the shaft of the forward chain wheel is keyed a miter wheel L which gears with another miter wheel L keyed on a shaft L. L, L are other miter wheels connecting the shaft L with a horizontal shaft M that passes through th pillar D. Upon the said shaft M are keyed two large chain'wheelsMM which drive endless chains-M 1 Fig. 2 that descend into the central charging well. An ordinary swivel tension wheel is provided at the lower end of the chains M which while maintaining the chains in tension permits them to follow the rotation of the mounting. M M are buckets carried by the chains M As the said buckets pass through the magazine they are-loaded with the charges, which charges are then elevated, as the gun runs out,bythe tappet L and chain L above described. As each bucket arrives at the top and passes over the chain wheels M the contents thereof are tipped out down a chute M which is carried by the mounting and is arranged to deliver the charges upon the floor near the breech end of the gun. When it is desired not to work the charge elevator by the gun all that is necessary to do is to raise the tappet L out of gear with the chain L. If desired the charge elevator may be operated by hand or it may be driven by a motor.

I provide my improved gun mounting with a recu'perator constructed as fOllOWSLN Fig. 4 is a cylinder formed in the cradle 15. N is a piston rod which projects through a packed gland in the rear end of the said cylinder N and is attached at its rear extremity to a transom N fixed to the frame 0. through a packed gland in the forward end of the cylinder N is a movable hollow plunger N which is secured to a cross beam N N, N are the tension rods of the recuperator. The

said rods are attached at their forward ends N and the liquid displaced'by the plunger N operates to force outward the hollow plunger N 3 thus compressing the recuperator springs and storing up energy therein which is utilized for subsequently running out the gun.

In Fig. 7 I have shown a simpler form of recup'erator which consists of a chamber N containing compressed air, and a plunger N which enters the said chamber as in the arrangement just described. W'hen the gun recoils the air in the'chamber N is still further compressed by the plunger N and energy is thus stored for running the gun out.

In'some cases I provide the mounting with a run out check to prevent the gun running out until required. This device is shown in Fig. 6. The plunger N in this case is made hollow.

O is a rod fixed to the forward end of the plunger N and which extends through the hollow plunger N. The said plungeris filled with liquid and is closed at both ends by packed glands through which the rod 0 can slide.

- O is a collar on the rod 0 forming a seat for an annular valve O which fits the interior of the rod N- and can slide to and fro between the valve seat and a stop 0 O is a small thoroughfare formed in the rod 0 and constituting a communication be-.

tween the two ends of thechamber of the .hollow plunger N on opposite sides of the valve v O is a valve spindle for closing the thoroughfare 0 when desired. The said spindle is secured to a hand wheel 0 which is screwed on the rear end of the -rod 0 so that by turning the said wheel the 'valve can be opened and'closed. When the gun recoils the rod 0 is carried back by the plunger N and the pressure of the liquid in rear of the valve 0 opens the said valve-so that the liquid has a Proj ecti n g free passage through the valve opening, and

offers no resistance to the recoil. Immediately however the gun begins to run out, the.

valve '0" is pressed to its seat and imprisons the liquid in the front end of the'chamber in the plunger N. Consequently the run out 'ator springs,

497,704 r g V I 3 upon the recuperator springs are free to run out the gun.

The above description assumes that the. valve is shut when the gun is fired. If however the valve is'open the gun will immediately commence to run out, and by regulating the amount of opening of the said valve the speed at which the gun shall run but may be adjusted as desired. It is obvious-that this automatic check may be applied to the air recuperator as well as to the spring recuperator. a
